Patent BE-904870-A (BE)
Title: Retractable barrage for water channel - has water ballast chamber and compressed air evacuation with water flow actuation
IPC: E02B7/44
Filed: 1986-06-03
Abstract: The barrage is rectangular and has a sealed ballast chamber with means of filling and expulsion of ballast by compressed air. In addition hydraulic pistons are provided to assist and control the articulation of the barrage. - When retracted the barrage lies flat above the floor cavity and the ballast chamber is full of water. To raise the barrage compressed air is used to expel the ballast. The water flow in the stream assists in the actuation of the structure. Air pressure is released to allow water to flood the ballast tank and lower the barrage. Hydraulic pistons complete the raising and can be used to control the speed of raising or lowering.

Title: Desulphurising steel - by pouring it onto lime in a dolomite -lined furnace
IPC: C21C1/02
Filed: 1972-02-25
Abstract: Method of desulphurisation of pig iron or steel melt in which using a vessel with a refractory lining esp. of dolomite, a sufficient quality of lime is introduced either preheated to >=1400 degrees C, or subsequently heated to that temp. by burners, and the melt is then poured onto the preheated lime. The desulphurisation produced is much more efficient than adding lime or Na2CO3 to the melt.

Title: Polytetrafluorethylene-polytriketoimidazolidine-solvent coating composition
Inventor: GEBAUER GERHARD
IPC: C08L79/04
Filed: 1975-03-25
Granted: 1979-09-25
Abstract: ABSTRACT The invention provides a high temperature resistant anti-adhesion and slide lacquer composed sub-stantially of finely distributed low molecular polytetra-fluorethylene, a polytriketo-imidazolidine resin and a solvent or solvent mixture.  The solvent is an aprotic organic solvent having a surface tension of more than 30 dyn/cm and the solvent is present in an amount by weight of from 0.43 to 100 times that of the resin.  The coatings obtained from the coating composition of the invention possess excellent anti-adhesion, smoothing and anti-tack properties comparable with those of pure, also high molecular weight polytetrafluorethylene, high abrasion resistance and resistance to mechanical strain and are still surprisingly tenacious and resistant to deep-drawing. At the same time, the adhesion of the coating to the substrate is not only equal but superior to that of known polytetra-fluorethylene coatings requiring an adhesive.  In addition, no roughening pre-treatment of the substrate is required.

Abstract: ABSTRACT OF THE DISCLOSURE       In distance measuring equipment (DME) for use in aircraft an interrogation is transmitted from a local airborne DME, generally to a ground station.  The transmitted signal is also sampled and transformed by a local oscillator means to the frequency of the expected response and applied to the front end of the DME receiver. The sampled and transformed signal thereafter traverses the receiver circuits and is applied to start a range clock at the rear end of the receiver.  Simultaneously, the signal traversing the receiver circuits is sampled and memorized in a sample and hold circuit.  A response to the interrogation, when received, is also applied to the front end of the receiver and traverses the receiver circuits and applied to stop the range clock, the resulting change of state of the range clock being related to the range between the interrogating and responding stations. The response signal traversing the receiver circuits is sampled and memorized in a second sample and hold circuit, with the contents of both sample and hold circuits being compared against one another.  The results of the comparison are applied to the local oscillator means to control the amplitude of the output signal thereof.

Abstract: ABSTRACT OF THE DISCLOSURE       An emergency trip device for applying pilot pressure to a pressure sensitive device during a resetting mode and for rapidly relieving pilot pressure from the pressure sensitive device during a tripping mode comprises a multivalve housing including a reservoir arranged for communication with the pressure sensitive device, an inlet flow cut-off valve operatively connected to the reservoir for controlling the flow of fluid to the reservoir and a disc-dump valve operatively connected to the reservoir for the rapid draining thereof.  Pilot fluid is supplied to the emergency trip device through fluid supply conduits and drained from the device through drain passages.  A trip valve is employed to provide fluid communication between the fluid supply conduits and a dump chamber employed in the disc-dump valve for the draining of the chamber to effect the opening of the disc-dump valve causing loss of pilot pressure to the pressure sensitive device during the tripping mode.  The trip valve and disc-dump valve are held closed in face sealing arrangements obviating any tendency of these valves to stick during the tripping mode due to foreign matter present in the pilot fluid.
